In my research, I focus on the experimental determination of the properties of the neutrino particle. The neutrino is the lightest weakly interacting particle that we know of, yet it is one of the most abundant of the elementary particles in Nature. Very difficult to detect, yet this particle opens a unique and clean window to understanding the lepton masses and mixings, and it also allows searching for new physics. It may also be the key to unlocking the mystery of matter-antimatter asymmetry in the Cosmos. Because of these exotic properties and their far-reaching role, research in neutrino physics fostered much development and progress in the past decades.
Today’s accelerator technology allows us to create high-energy beams of neutrinos. They traverse the Earth’s Crust, and by sampling their beam with specialized detectors and using advanced computing techniques, we can measure the properties of this elementary particle. I participate in the currently running Tokai-to-Kamioka (T2K, Japan) and the upcoming Deep Underground Neutrino Experiment (DUNE, USA) long-baseline neutrino-beam experiments. T2K recently revealed the first signs of possible Chare-Parity-symmetry (CP-symmetry) violations in the lepton sector of the elementary particles. The upcoming DUNE experiment will measure the value of the CP-symmetry violation with unprecedented precision, along with several other properties of the neutrino particle. To achieve such a level of precision, however, the neutrino beam, neutrino-nucleus interaction modes, all the detectors, and other experimental results will need to be modeled and their uncertainties accounted for. This involves orchestrating hundreds of experimental components correctly and contrasting simulations with data. In my research, I am working on developing the statistical modeling of T2K and DUNE, ensuring we extract the best possible information from the experiment.
